Ok , now that you've had your say (and you did well) you need to let go and focus on YOUR life. Are you living your dreams? If not, what is holding you back?
I know he said a lot of things that you might read as hopeful - but let's be real here. This is a man who has cheated on you 5 times (that you KNOW of) with two of those being long term affairs. He has deep serious problems beyond simple depression and you should NOT consider taking him back unless he has done a LOT of work (say, for example, a year of individual counseling and 12 step meetings for sex addiction).
More likely he has a personality disorder (like narcissism) or just a serious moral character defect.
Now I grew up Catholic and I understand people who would not date or marry again if their spouse divorced them. If those are your beliefs, then fine - that's your choice to make. But you must ask yourself why you don't believe you deserve more? Would you advise your daughter to stay in a relationship with a man who was a serial adulterer?
Despite everything he said yesterday, I predict he will move ahead with moving in with the OW. Let go or be dragged. Focus on YOUR life and let go of him - he is years away from being ready to reconcile, if ever.
